What Is a DUNS Number?

Whether you plan on doing contract work with a government organization or just want to separate your business credit from your personal credit, a DUNS number can help.

A DUNS number (an abbreviation for for Data Universal Numbering System) is a unique nine-digit identification number that verifies the existence of a business, globally. Think of it as a social security number for your business. The DUNS number is assigned by Dun & Bradstreet (D&B) for each physical location of a business, and is used by industries and organizations around the world as a global standard for business identification and tracking.

You'll need a DUNS number for your business if you plan to:

• Provide contract work for any government organizations
• Get approved for a business line of credit
• Work with specific industry and trade associations
• Separate your personal assets from your business

Typically, business owners register for a DUNS number with Dun & Bradstreet following the legal formation of their company. D&B requires the following information about your company:

• Business name
• Physical mailing address
• Company formation date
• Nature of the business
• Name(s) of principal(s)
• Industry classifications (i.e., SIC, NAICS)
• Payment and financial experiences

Typically, your DUNS number will arrive via mail 45 days after you register. However, you can purchase an expedited process and your number arrive within five business days.

The DUNS number is free. However, if you wish to receive your number faster than the standard 45 days, you can purchase an expedited process from D&B for $229.

There are few different ways to get a DUNS number. You can visit D&B's DUNSFile page or call 1-866-374-0441.
